Rather than think about the mechanical details of their swing, [expert] golfers should focus on general aspects of their intended movement, or what psychologists call a “holistic cue word”. For instance, instead of contemplating things like the precise position of the wrist or elbow, they should focus on descriptive adjectives like “smooth” or “balanced”. An experimental trial demonstrated that professional golfers who used these “holistic cues” did far better than golfers who consciously tried to control their stroke.

Reading this book a couple of years ago quite honestly transformed my tennis game: I am good at deliberate practice, which had allowed me to become technically very sound, but until then I was completely unable to consciously enter a state of relaxed concentration and execute in a match situation: I was a classic “over thinker”. Gallwey’s book treats relaxed concentration as a skill to be deliberately practiced, and gives an approach to do so. Highly recommended, and fascinating for any (thoughtful) sportsman.
